This is a case resolution from the Department of Defense's All-Domain Anomaly Resolution Office (AARO), dated 8 May 2023, about a 2021 report from military airspace in the Western United States. Military personnel saw five equidistant infrared lights flying at a fairly constant pace and thought they might be an incursion into restricted airspace. AARO and its partners concluded the objects were almost certainly commercial aircraft on established air routes up to 300 nautical miles from the sensor. The page was cleared as unclassified and released in full in February 2025.

Case: "Western United States"
Case Resolution I 8 May 2023
(U) Key Findings
(U) AARO assesses that the UAPs in this case
were almost certainly commercial aircraft
travelling on well-established air corridors as far
as 300 nautical miles from the platform, based
on a thorough review of the data by multiple
analytical and scientific entities.
• (U) Military personnel reported seeing five
equidistant lights that they believed
represented a potential incursion into
restricted military airspace.
• (U) AARO's Intelligence and Science and
Technology (S&T) partners independently
came to the same conclusion in accordance
with AARO's analytic framework.
• (U) The objects strongly correlated with
specific commercial aircraft travelling on
different air routes up to 300 nautical miles
from the sensor.
(U) Intelligence Assessment
(U) Analysis of the objects' positions and
acquisition of additional data led AARO to the
conclusion that the objects were significantly
farther from the platform than originally
estimated by the observers.
(U) Case Essentials
(U) Military personnel reported this case
due to the observed UAP presenting a
potential incursion into restricted
airspace. The UAP were described as
equidistant lights that flew at a relatively
constant pace
(U) Location: Western United States
military airspace
(U) Date(s): 2021
(U) Altitude: Between 20,000 to 40,000
feet
(U) Shape: Oblong dots/lights
(U) Reporter: Military personnel
(U) Sensor: Infrared (IR)
(U) Behavior: Equidistant lights that
flew at a relatively constant pace
(U) Case Status: Resolved; the lights
were aircraft up to 300NM away from the
sensor
